Sorry for the late response.
Yes, I set the fan speed to max in this patch when user set high performance.
Considering that: 1. set fan speed to max is helpful to let GPU run under
highest clock as long as possible.
2. avoid GPU rapid temperature rise in some case.
OK, I guess you know if it's needed or not.
It is somewhat annoying noise wise, maybe one day there will be a way
for users to set fan back on auto?
Accepting I don't know how the h/w works your point 2 would imply that
with perf on auto doing something like running a benchmark that pegs
all the clocks high should also instantly force fan high?
I don't think that would be popular WRT noise.

in profiling mode, powerplay will fix power state as stable as

profile_standard: as a prerequisite, ensure power and thermal

as possible.
profile_min_sclk: fix mclk as profile_normal, set lowest sclk
profile_min_mclk: fix sclk as profile_normal, set lowest mclk
profile_peak: set highest sclk and mclk, power and thermal not

profile_exit: exit profile mode. enable gfx cg/lbpw feature.
Testing R9 285 Tonga on drm-next-4.11-wip
This commit has the effect that doing
echo high >
/sys/class/drm/card0/device/power_dpm_force_performance_level
instantly forces fan to (I guess) max, where normally it doesn't
need anything like as fast with the clocks high when doing nothing else.
Ping - just in case this got missed, still the same on current
drm-next-4.11-wip
Just a heads up, Rex was looking at this, but it's Chinese New Year this week.
OK, thanks & Happy new year.
